Scawen and Co. have released a new patch for Live For Speed S2. It includes a few changes and adresses some problems people were having with the patch that was released about a week ago. Here's the blurb:

We are very pleased with the reaction to the S and T versions. Various fixes and improvements have been done in the week since version S was released. Thanks to all who tested and commented on the test patches. Patch U is quite an improvement and we expect this to be the stable version for some time while we have a little break then get on with more S2 work, on the way to S2 final.

Download mirrors and discussion for patch U can be found in this thread on the Live for Speed forum.
